FltIsIoCanceled function

Description

The FltIsIoCanceled routine checks if an IRP-based operation has been canceled.

Parameters

CallbackData [in]

Pointer to the callback data structure for the operation (FLT_CALLBACK_DATA).

Return value

FltIsIoCanceled returns TRUE if an IRP-based operation has been canceled and FALSE if the operation has not been canceled or if it is not an IRP-based operation.

Remarks

It is a programming error to call FltIsIoCanceled for an operation that is not IRP-based. To determine whether the operation is IRP-based, use the FLT_IS_IRP_OPERATION macro.
